A biodegradable tire includes an elastomeric matrix and a shape memory alloy scaffold integral with the matrix. The elastomeric matrix includes (by weight of the matrix) a flax seed material derived from 14% to 19%, a guayule-derived natural rubber from 55% to 65%, a metal oxide from 12% to 15%, a carbon-based filler from 9% to 12%, and one or both of an antioxidant and an antiozonant, each from 1.8% to 3.1%. Further, the tire is airless. In addition, the shape memory alloy scaffold comprises a Ni—Ti shape memory alloy, a Cu—Zn shape memory alloy, or a combination thereof.
